[BUG] Can't group control for OpenThread device

[myddpp]

Reproduction steps

When testing the wifi device in the same way, group control works.

This is not the case for thread Demokit devices.

Is another procedure required to group control thread devices?

Below is the method I tested.

`0. pairing
./chip-tool pairing ble-thread 3 hex:0e080000000000010000000300000f35060004001fffe0020811111111222222220708fd1758cddf0caf40051000112233445566778899aabbccddeeff030e4f70656e54687265616444656d6f010212340410445f2b5ca6f2a93a55ce570a70efeecb0c0402a0f7f8 20202021 3842

1. write acl
   ./chip-tool accesscontrol read acl 3 0
   ./chip-tool accesscontrol write acl '[{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": [112233], "targets": null },{"fabricIndex": 1, "privilege": 4, "authMode": 3, "subjects": [3], "targets": [{"cluster": 6, "endpoint": 1, "deviceType": null}, {"cluster": 8, "endpoint": 1, "deviceType": null}] }]' 3 0

./chip-tool groupkeymanagement key-set-write '{"groupKeySetID": 42, "groupKeySecurityPolicy": 0, "epochKey0": "d0d1d2d3d4d5d6d7d8d9dadbdcdddedf", "epochStartTime0": 2220000,"epochKey1": "d1d1d2d3d4d5d6d7d8d9dadbdcdddedf", "epochStartTime1": 2220001,"epochKey2": "d2d1d2d3d4d5d6d7d8d9dadbdcdddedf", "epochStartTime2": 2220002 }' 3 0

./chip-tool groupkeymanagement write group-key-map '[{"groupId": 2, "groupKeySetID": 42, "fabricIndex": 1}]' 3 0

./chip-tool groupkeymanagement read group-key-map 3 0
./chip-tool accesscontrol read acl 3 0

2. create group
   Next, program the chip-tool:
   ./chip-tool groupsettings add-group groupName groupId
   ./chip-tool groupsettings add-group grp2 0x0002

./chip-tool groupsettings add-keysets keyset Id keyPolicy validityTime EpochKey
./chip-tool groupsettings add-keysets 42 0 0x000000000021dfe0 hex:d0d1d2d3d4d5d6d7d8d9dadbdcdddedf

./chip-tool groupsettings bind-keyset groupId keysetId
./chip-tool groupsettings bind-keyset 0x0002 42

./chip-tool groupsettings show-groups
./chip-tool groupsettings show-keysets

Next, add bridge endpoint 3 to Group ID 0x0002:
./chip-tool groups add-group GroupID GroupName destination-id endpoint-id-ignored-for-group-commands
./chip-tool groups add-group 0x0002 grp2 3 1

./chip-tool onoff toggle 0xffffffffffff0002 1

@myddpp Are the devices joining the relevant multicast groups? Do you have access to the device logs?

#27631 talks about some Thread devices not being configured to support enough groups, but certainly says that just one group should work fine.
